Dimethylamine → 1-Benzhydryl-N,N-dimethylazetidin-3-amine

Participants

Reaction Steps

5% Palladium-carbon (1.5 g) was added to 1-benzhydrylazetidin-3-one (1.50 g) obtained from Referential Example 100 and 40% aqueous dimethylamine (4 mL) in methanol (30 mL). The resultant mixture was subjected to catalytic reduction in a hydrogen atmosphere overnight. The catalyst was filtered off, and then the solvent of the filtrate was evaporated under reduced pressure. The residue was purified through silica gel column chromatography (chloroform-methanol), to thereby give the title compound as a solid (1.55 g, 92%).
